摘要
通过对某火电厂发电机定子接地故障发生经过进行分析研究,查找故障发生原因,得出此次发电机定子绝缘故障是由过渡引线螺栓紧固不良和散热不良引起,同时指出了运维中存在的问题,并提出了防范措施及建议,可为解决发电机同类问题提供参考.
Abstract
By analyzing the stator grounding faults of turbo-generators in a thermal power plant to search fault causes with the findings that the generator stator insulation faults are caused by the poor fastening and cooling of transition lead bolts.Meanwhile,the problems existing in operation and maintenance are pointed out,and the preventive measures and suggestions are put forward,which is available for reference in handling similar problems of the generators.
